Answer:
Mutualism
Explanation:
In biology, the term <em>symbiosis </em>refers to close and often long-term interactions between organisms that belong to different species. There are three main types of symbiotic relationships:
- mutualism - both organisms benefit from their relationship
- commensalism - one organism benefits, while the other doesn't benefit or suffer any harm
- parasitism - one organism causes harm to the other
In the given scenario, both the bird and plant benefit from their relationship. The bird gets food, while the plant reproduces more easily. This is why their relationship is an example of mutualism.
Answer :B. By changing the shape of the enzyme's active site.
check the attachment
Explanation: This is a type of inhibition , in which a molecule binds to another part of the enzyme instead of the active site.
On binding, it disrupts the normal hydrogen bond and hydrophobic interactions holding the enzyme molecule in its three dimensional shape, therefore distorting the conformation and ACTIVE SITE of the enzyme (changed it shape).
Since the active site is the precise location enzyme must bind with substrates for enzymatic reactions,this makes the enzyme not fit for binding with the substrate, therefore the efficiency is reduced. No substrate-enzyme complex, and hence no substrate-product complex for the release of products, this brings down the turnover rate and eventually
<u>the rate of reaction of the enzyme</u>
Thus, the enzyme function is totally blocked, even in high concentration of the substrate,
